As I've posted in other threads we've also been having trouble keeping our 10.4.3 servers up. Most recently it has been file handle problems.


Last night my tech was able to reproduce a problem which he reported to Apple. We are interested to know if anyone else is seeing this/can reproduce it.

Here is his emails to me from last night (they are little rambling because it was so late but he describes it better than I can).



And here is another one...

Hmmm :
AppleFileServer was sick on FlowX. I just restarted that service.

It was having a too many open file handle type thing too??
It had over 10,000 file handles open.

It was still servicing some requests kind of slowly and not really properly.

I wonder if I had reduced sysctl kern.maxfilesperproc too far?? (and
then it went into a tail-spin after being denied the first time?)
Have just bumped both numbers way up (furhter):

kern.maxfiles = 100000
kern.maxfilesperproc = 30000

on second thoughts maybe I'll try:
kern.maxfiles = 400000
kern.maxfilesperproc = 100000

[AppleFileServer doesn't follow Apple's current philosophy of one
process per connection ... it doesn't even fork - just one process does
all of the work (using threads within) - and there appears one process
that does some monitoring or perhaps handling of the incoming
connections before handing over to the main process.] ... It was
throwing over 100 error messages per second into:
/Library/Logs/AppleFileService/AppleFileServiceError.log
line is:
01/Dec/2005:14:05:42 1000: TCP Listener returned error on accept

(I'm betting it is a total FileHandles problem
