The application uses message queues for IPC. I used the compiler option<BR />-D__BIGMSGQUEUE_ENABLED to have a larger message queue; but the program is unable to create the queues. I have already set the msgseg-&gt; 8192; msgssz-&gt;64; msgmnb-&gt; 262144 and rebuilt the kernel and re-booted the system. Is there some other parameter to be set which I have missed?<BR />Regards,<BR />Amit Gupta Mon, 24 Sep 2007 06:39:57 GMT https://community.hpe.com/t5/operating-system-hp-ux/message-queues-problem/m-p/4074892#M735448 amit1209 2007-09-24T06:39:57Z https://community.hpe.com/t5/operating-system-hp-ux/message-queues-problem/m-p/4074893#M735449 Amit,<BR /><BR />The following patches will allow you to increase message queue capacity <BR />(msgmnb) from 64Kb to 64Mb. <BR /><BR /> PHKL_26136 dyn semaphores; large data space; msgmnb <BR /> PHKL_24487 LP64 maxdsiz; max msgmnb; major no; maxfiles <BR /> PHKL_26008 pstat patch, long command line storage <BR /><BR />NOTE: Be sure to check the ITRC Patch Tool to locate the most current version <BR />of this patch. <BR /><BR /><BR />WK Tue, 25 Sep 2007 03:54:16 GMT https://community.hpe.com/t5/operating-system-hp-ux/message-queues-problem/m-p/4074893#M735449 whiteknight 2007-09-25T03:54:16Z
