I'd like to know what flash is! I never saw that.any idea why my "flash" is taking up so much memory ?
/sys check-disk
well logging.. i only have the standard login and also a duplicate of some to forward it to a syslog server'Flash' process is writing to flash memory (NAND).
Check your settings about logging/graphing.
Something is permanently writing NAND, also check in Winbox
System/Resources/Total Writes.
HTH,
okie will try and and get back to youperhaps you shouldthe router will reboot once you apply itCode: Select all/sys check-disk
There is problem with cable to ether2. Try to change itand i've notice a "Weird" problem why has it rebooted and my int2 went to 10mbits mode ??
the thing is.. my cables are connected to eth1, eth3, and etc5There is problem with cable to ether2. Try to change itand i've notice a "Weird" problem why has it rebooted and my int2 went to 10mbits mode ??
okie.. any idea.. where section to check in particular ?@forces2010
Not connected master port always shows 10Mbit, half-duplex.
Your screenshot shows that you have over 120.000 NAND writes.
I dont know what is your RB total uptime but as some comparison,
RB750 which is running over two years has 3.500.000 writes.
As I wrote earlier something writes your NAND permanently, check your config.
yeah.. through all my experience troubleshooting.. network/system/performance issues..forces2010 - I am having a similar problem to you, which I have documented here - but basically when I use wifi and a skype call, I get high 'flash' usage, and I have not been able to get to the bottom of the issue.
I will be watching this thread with interest.
They got back to me to say they couldn't reproduce the problem. I should try a different PSU (tried many with no difference) or a different unit (not easily possible for me) and then report back.I'm currently using an RB750GL and was considering getting a RB751U-2HnD when I came across this thread. Has Mikrotik got back to any of you regarding this prob? I'm just afraid that I will end up with the same prob.
Do you have any information about why the NTP package could cause a problem? And any advice for keeping accurate time without it?Disable the 'calea', 'ntp' and 'lcd' packages, and see if the NAND problem goes away. Especially the 'ntp' package.
damn that sucks, guess we need to wait until a new revision of the board to come out.. or a newer version of rOS ,They got back to me to say they couldn't reproduce the problem. I should try a different PSU (tried many with no difference) or a different unit (not easily possible for me) and then report back.
I'm using a separate (non mikrotik) wireless access point and having no troubles now.
kinda doubt those packages are using the flash....Disable the 'calea', 'ntp' and 'lcd' packages, and see if the NAND problem goes away. Especially the 'ntp' package.
done.. sent the supout.rif files to support already...have you made that support output file while you are using RouterOS v5.13 and the cpu usage is close to 100%?
Send that file to support@mikrotik.com
Interesting. But I don't use the NTP package and still had problems.The 'ntp' package has this uncanny ability to restart Routerboards without warning. Those 3 packages I mentioned are usually not included in a standard RouterOS installation either.
I don't use either of the other packages. Do you use Skype over wireless? And do you use any Apple hardware? Would you mind posting your wireless and bridge config to see if I did anything "wrong"?How about the other two, if you have it? What is your /system package print output? I use Skype too with exactly the same routerboard and has no problem.
Yes I use Skype over wireless. My household is Apple-free though, we don't have those things here. Only Skype on Windows Vista.I don't use either of the other packages.

You're right, MBP connects at 300mbps to my Airport Extreme at 5Ghz only. It seems Apple decided not to enable 40Mhz width at 2.4GHz. I read that if one boots up Windows using Bootcamp, it will connect just fine at 300mbps at 2.4GHz.Would be interested to hear how the Skype call goes - thats the only way I can replicate the 100% CPU and flash process. Downloading (even multiple legal torrents on a 100mbps fibre connection) works fine.
I think you need a 5ghz card to connect at anything over 130mbps to your Mac.
what error did you get ? upon reboot the first line , is the error code , code 1 ?2 hours ago, while I was out, the RB751U-2HnD decided to reboot itself. I wonder what happened. At that time I only had one Mac connected to it downloading 3 torrents simultaneously (part of my stress test). I wasn't home but got notification of it when it emailed me its new IP address.
I am using The DudeAny one of you use the Dude maybe? To monitor the router?
No, in the version 5.22 is also not okay with the heavy load of the process "flash". Look here:Same problem with 6.0rc5, downgraded to 5.22 and everything seems to de fine.
