Do you have a limit on the number of processes a user ID is running can create on Solaris?
I have had a situation before on AIX with lots of connections, where MQ seemed fine, but applications were failing because the processes running under the mqm user ID had hit the user ID max process limit. Remember, for every connection an agent process is spawned under the mqm user ID to handle the connection. Different platforms have different agent-application connection ratios (on AIX I believe it is 1:1 - Solaris may be different).

Dear MQ Specialists, Would anyone be able to comment the problem described below ? We have a very similar problem: We use WebSphere MQ 5.3 for Solaris (Solaris 5.8). There are about 100 applications connecting to MQ using the binding mode (ie server, ie local connections, NOT client connections through a channel). After we reach a certain load on the machine where the applications and MQ run, MQ starts returning error code 2009 to any MQI call. Due to the documentation this could happen if the QMGR goes down, nevertheless, we checked the QMGR, IP listener and logs and we cannot find any problem there. QMGR is running and in the log, there are no messages at all. What may be important, we do not have installed any higher CSD as there was a registered problem with a Solaris Patch (MQ patches and Solaris patches cannot coexist on the machine). We will try to remove the Solaris patch and install current CSD on MQ, if it helps. But, any comments would be welcome - has anyone seen this problem ? Does anyone have any advice ?

I seeing (with intermittent regularity) a bunch of 2009 reson codes in server applications on site here. The applications concerned are server apps (C++, no Java), running on the same box as the queue manager and are using server bindings (linking with libmqm.so), and connect using MQCONN, supplying the queue manager name (there is no default queue manager defined). Additional info: * Solaris 5.8 * MQ 5.2 CSD06 (I know CSD07 is availbale) * Applications linked with libmqm.so * There are no MQ environment variables defined (no MQSERVER). * This host has only two queue managers defined. * The queue manager is a member of a cluster (six qmgrs total). I'm not getting anything obvious in the error logs (neither the global or the queue manager local). Nothing that would indicate a server error prior to the application getting a reason code of 2009. -- tonyB.
