panic: lock_set

I have a program running on a Sparc 20 machine with Solaris 2.4 (SunOS 5.4) and using Motif 1.2.?.  I am using some of the Timer Callbacks with Motif as well as some serial, socket, and timer "interrupt" routines that we have developed.  I have received the following error mainly after letting the program run overnight:

      panic: lock_set: lock held and only one CPU

This shows up in the /usr/adm/messages after the hard reboot when such an error occurs.  What I am looking for is what would cause such an error.  I am not doing any locking on my own so it could be internal to the libraries I am using.  This was a problem early on in the project and is not repeatable nor consistent.  Now that the project is coming to an end, I would like to get this issue resolved.

Your timer interrupt routines may be the culprits.  Interrupts are not completely safe when used with X.  If you want to do something on a periodic basis, you should use XtAppAddTimeOut() so that the main event loop is your mechanism for everything.  

This shouldn't have caused a panic, but then I don't have enough information from your question to judge.
