vmunix: proc: table is full

[ITeam]

Hi I have an RX6600 11:23, received the above message, kernel params as follows:

maxfiles 2048 Default
maxfiles_lim 4096 Default Immed
maxuprc 256 Default Immed
nproc 4200 Default Immed

I have attached a sar -v output list-

22:21:00 N/A N/A 234/4200 12972 1071/255140 0 1267/65536 0

It looks like at 19:41; 19:51; 22:21 and 22:31 that the proc-sz overflowed - however the number of precesses are well within their respective setting, I've looked through all other sar logs and haven't seen this before. I'm not sure about increasing nproc or maxuprc as proc-sz never seems to go over 1000 let alone near 4200 ......

has anyone any advice or seen this before?

Many thanks!

Yes I've seen this post; however my question is - the thresholds don't appear to be getting hit so I'm not really certain that increasing nproc or maxuprc is going to fix this as there maybe an underlying issue.

Has anyone seen this before?

Shalom,

Glance gpm has a good high water mark display to catch parameters being exceeded.

These parameters which are all at default are too low for a busy database server.
maxfiles 2048 Default
maxfiles_lim 4096 Default Immed
maxuprc 256 Default Immed
nproc 4200 Default Immed

By default other parameters depend on these as well.

I would increase them and remove formulas within the kernel for limits.

Hi,

Unless or until the nproc value reach the max limit you won't get this error "vmunix: proc: table is full" . It may be possible that some script or job might have started so many processes at that point of time.

I have increased kernel parameters.
