hi i have a some catalyst 2960, in my core network, but sometime any management

access to these devices is not possible ( telnet,ssh or console access). when

i try physical access (console) i have this log message "low on memory, try later".

my cpu usage is max 7%

my IOS version is c2960-lanbasek9-mz.122-44.SE1.bin

after reboot, all these acces are possible again, but this is not a

best solution because this probleme is come 2 time already, i thinks it will come agains.

before this event arrived , i saw (in sh memory output )processor free memory decrease to 0

after reboot the sh memory command give this and atually decrease again, i don't know why.

It could be a memory leak or a bug. It could be something like you do not have exec timesouts on your vty sessions and console sessions which ties up all your vty's and sucks up the memory . Look for bugs for 12.2.44 , though thats pretty new and I wouldn't expect that.
