| |
Hello,
I have encountered dst cache overflow errors yesterday, the network traffic has slowed down, pinging the machine would result in lost packets. Here is a part of system log:
Nov 25 15:40:37 www kernel: NET: 510 messages suppressed. Nov 25 15:40:37 www kernel: dst cache overflow Nov 25 15:40:42 www kernel: NET: 399 messages suppressed. Nov 25 15:40:42 www kernel: dst cache overflow Nov 25 15:40:47 www kernel: NET: 375 messages suppressed. Nov 25 15:40:47 www kernel: dst cache overflow Nov 25 15:40:52 www kernel: NET: 253 messages suppressed. Nov 25 15:40:52 www kernel: dst cache overflow
After restarting apache and mySQL the machine seemed to catch up again, with only a few occasional dst overflow messages.
the kernel is 2.2.12 SMP compiled with gcc version egcs-2.91.66 19990314/Linux (egcs-1.1.2 release)
the machine is 2 x PIII Xeon/500MHz with 512 MB RAM, ethernet controller: Intel 82557 (rev 8) scsi: NCR 53c896 (rev 1) and NCR 53c810 (rev 35)
this machine is used as www/SQL server (intensive disk I/O and network load)
I have noticed several other messages describing the same problem posted to this list on various kernels (2.2.5 and 2.3.15, 2.3.19), some resulting in kernel panic - is there any solution?
thanks,
