Version: 7.1 | Keywords:
Testcase: | Blockedby:
Os: Linux | Blocking:
Architecture: x86 | Failure: Runtime crash
-----------------------+----------------------------------------------------
My program is crashing at runtime with the error below. The program is a
multi threaded network server and the crash happens when around 1000
clients are connected. The crash happens when compiled with -threaded, and
also when run interpreted with runghc (without -threaded)
Thanks
