This is familiar to me. UNIX is throwing the "[EMFILE] Too many open files" error because you have reached a limit of open files. You'll need to tune the kernel a bit to allow for more open files on the system and possibly per process. Solaris used to need tuning more than others like HP-UX or AIX, but I haven't messed with Solaris 10 lately so I don't know how dynamic its kernel is.
Would seem to suggest why UV sessions hang during this condition as well.

We are doing this for many years already but with one of our accounts we have now hit a problem that we are unable to explain. There are 2 distinct problems that one some levels seem related in some ways but in others not at all. Problem one, one particular big report opening many (some distributed) files hits some sort of maximum and then fails with: Unable to open pipe for tsort process. [EMFILE] Too many open files During the "open" statement trying to open one more file. A problem is that this specific error is not reproducible on different systems running the same Universe/OS/Application versions. The second problem is that at certain points in time the whole universe environment freezes, every process that tries to do a "open" statement hangs indefinitely, the processes are not killed even when users disconnect, leading pretty quickly to a "out of licenses" situation. The two seem related in the fact that both problems have to do with the "open" statement however the effects are rather different. Running on Solaris 10 with Universe 10.1.18 on Sparc hardware. I'm hoping that this sounds familiar to you and that you might have found a solution to this problem if so, please help! (actually I'm hoping for you that you are not familiar with the problem as it is a rather nasty one ;-)) Any insights are a appreciated, more information can be provided if that were to be helpful.
