samba - Dec 2001 - Out of connections: here too

Hi samba fans,

We run samba on Solaris SunOS 5.8, samba 2.2.2 and are plagued by failing 
connections for a while.

We have about 150 people at max usage connecting simultaneous to 1 samba 
server, mostly from within Win NT Terminal Server Sessions (this might be 
related, as these sessions occur from only from four different IP's namely 
our four TS servers)

Symptom:
user cannot mount one or more shares they previously were able to, only 
occurs on peak hours. 

- Things we tried
(updated from 2.2.0 -> 2.2.2)
increased max files for solaris
launch from inetd

We used to have this message (smb.log) under heavy load in 2.2.0

---2.2.0 samba.log----
[2001/09/20 13:15:21, 0] lib/debug.c:reopen_logs(335)
? Unable to open new log file /var/log/samba.log: Too many open files
-----------------------

Now (2.2.2) we are having the following, same basic problem it seems (same 
symptoms)

---2.2.2 samba.log---
[2001/12/19 15:08:56, 1] smbd/conn.c:conn_new(104)
  ERROR! Out of connection structures
[2001/12/19 15:08:56, 0] smbd/service.c:make_connection(325)
  Couldn't find free connection.
-------------------------


The Out of Connections thread triggered me as I have very similar problems.

btw Im pretty sure our sun admin did a clean install when upgrading, he 
installs everything in it's own single sw path, only linking things to where
they belong. 

Any suggestions are utterly welcome, if only to shut the win admins up ;-)

According to the sun admin, this is set to unlimited.

Also, from docs.sun.com he gets the info that compiling 32bit apps on Solaris 
limits that app to 256 file descriptors, A 64-bit compiled program using 
standard i/o can use up to 2 billion descriptors.

plimit (according to sun docs again) is an alternative, but that too seems 
already be set to unlimited.

Perhaps we need to compile 64 bits, which is costly, as SUN charges much for 
that compiler.

As this may be interesting info, samba is cc'ed again.

Can you grep source for thess strings and look there?
