Hello
I got this error today in my 3550 switch's log:
Nov 19 11:00:29.647 UTC: %LINK-5-CHANGED: Interface FastEthernet0/18,
changed state to administratively down
Nov 19 11:00:38.907 UTC: %LINK-3-UPDOWN: Interface FastEthernet0/18,
changed state to up
Nov 19 11:00:39.203 UTC: %SYS-2-MALLOCFAIL: Memory allocation of 1680
bytes failed from 0x161B38, alignment 0
Pool: I/O Free: 6752 Cause: Memory fragmentation
Alternate Pool: None Free: 0 Cause: No Alternate pool
-Process= "Pool Manager", ipl= 0, pid= 5
-Traceback= 1A57D0 1A6DF4 161B3C 1B2BF0 1B2E38 1C6440
Nov 19 11:00:44.495 UTC: %PM-4-ERR_DISABLE: dtp-flap error detected on
Fa0/18, putting Fa0/18 in err-disable state
Nov 19 11:00:46.499 UTC: %LINK-3-UPDOWN: Interface FastEthernet0/18,
changed state to down
Maybe it's a memory leak or the PC (Win2000) creates this error
which is in the Fe 0/18?
Do You need output of the "show tech-support"?
