Hi everyone,
I got the following message in the system log:
/kernel: pmap_collect: collecting pv entries -- suggest increasing
PMAP_SHPGPERPROC
The machine being more than 200km away, I cannot compile a new kernel
right away. So I was wondering if there are any tweaks that I can do
'remotely', to solve the problem at least temporary.
The machine in question is serving as a web server (apache + php +
phpaccelerator), and has 1GB of RAM. The following are some infos I could
find about the shared memory:
(9:53) bgd@(adserver)[~] ipcs -M
shminfo:
shmmax: 33554432 (max shared memory segment size)
shmmin: 1 (min shared memory segment size)
shmmni: 192 (max number of shared memory identifiers)
shmseg: 128 (max shared memory segments per process)
shmall: 8192 (max amount of shared memory in pages)
(9:53) bgd@(adserver)[~] ipcs -a
Message Queues:
