Hi all,
system: ES45, 4cpu, 8GB, 5.1B PK2
I'm getting very slow cpu rsponse to, in particular,
network-related requests. So far, all I can see that is
abnormal is a very high 'sys int' count in vmstat:
alf1_tsh> vmstat 1
Virtual Memory Statistics: (pagesize = 8192)
procs memory pages intr cpu
r w u act free wire fault cow zero react pin pout in sy cs us sy id

16 1K 50 344K 570K 104K 269 89 76 0 103 0 1K 5M 2K 50 50 0
The 5M system calls a second sometimes reaches 8M and is normally
between 1 and 5K.
Is there some way I can find the process making these system calls?
So far, looking at the ps options:
minflt, majflt, pagein, nsignals, inblock, oublock
has revealed nothing.
Network activity seems normal:
