I just upgraded a machine to -STABLE as of about 3 days ago and am now
getting "camq_init: - cannot malloc array!" reported on the console.
vmstat suggests that M_DEVBUF has reached its limit:
Type InUse MemUse HighUse Limit Requests Limit Limit Size(s)
devbuf1293222 20988K 20988K 20988K 9050825 2 0 16,32,64,128,256,512,1K,2K,4K,8K,32K,64K,128K
When I reboot, devbuf returns to a sane value:
devbuf 870 788K 788K 20988K 18891 0 0 16,32,64,128,256,512,1K,2K,4K,8K,32K,64K,128K
It looks like something is leaking M_DEVBUF objects, but given that
every device driver in the system uses M_DEVBUF, it mightn't be easy
to locate. Has anyone else seen anything like this?
The system was previously running a 4.6-PRERELEASE from mid-May and did
not report any problems.
It's a Compaq Proliant 1850R and the full dmesg is:
