"Unable to create Mutex"
I'm trying to run a software package on RHAS 4.0 that I know to work on RHES 4.0 (required to switch platforms by a 3rd party). When doing so, I get the message, "Unable to create mutex; possibly not root or insufficient resources" (EDIT: Actually, it's RHAS 4.0 64-bit. The package is still compiled as 32 bit.)
The only returns I get on a google search for this message (or even various substrings of this message) are a couple links to some board called chinaunix, which look to be a dead end anyway. I know the message isn't in my code.
I know our software is a heavy consumer of semaphore arrays, but the maximums and used resources prior to operation are exactly the same as the other platform. I tried doubling the number of arrays in /proc/sys/kernel/sem via sysctl.conf but that doesn't help.
At a loss for solutions, I'm currently greping the whole tree for this message. ANY input or suggestions would be appreciated.
