Hello,
I seem to have an issue with the l2arc _feed_thread using a high percentage of cpu. Below is my system information
FreeNAS Build FreeNAS-8.0.4-RELEASE-x64 (10351)
Platform AMD Athlon(tm) II X2 270 Processor
Memory 16367MB
System Time Wed Apr 4 21:12:23 2012
Uptime 9:12PM up 26 days, 22:12, 1 user
Load Average 0.85, 0.85, 0.81
OS Version FreeBSD 8.2-RELEASE-p6
Here is the top snapshot.
PID USERNAME PRI NICE SIZE RES STATE C TIME WCPU COMMAND
11 root 171 ki31 0K 32K RUN 1 623.8H 95.36% {idle: cpu1}
178 root -8 - 0K 60K CPU0 0 49.5H 79.05% {l2arc_feed_threa}
11 root 171 ki31 0K 32K RUN 0 598.3H 29.20% {idle: cpu0}
0 root -16 0 0K 928K - 0 129:27 0.00% {zio_read_intr}
2363 root 44 0 31004K 18184K kqread 1 52:10 0.00% {connthread #0}
12 root -32 - 0K 224K WAIT 1 52:09 0.00% {swi4: clock}
You can see process 178 is using 79% of the cpu and has been doing so for the past 2 days. Ive searched for this error on other sites, some of them reference the clock_t overflow. Is there a fix for this issue?
