#15010: Application (warp) server crashing periodically with "TSO object entered" -------------------------------------+------------------------------------- Reporter: ramirez7 | Owner: (none) Type: bug | Status: infoneeded Priority: normal | Milestone: 8.10.1 Component: Runtime System | Version: 8.0.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: Runtime crash | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by sseverance): I hit something similar last night. Unfortunately I don't have a way to make a repro but will provide what information I do have in case it helps eventually. Our app is a server, although not a web server. We make extensive use of the STM and there may be hundreds of threads running at a time. I would say there are a moderate amount of exceptions, mostly forced on us from their use in other libraries, as we tend not to use them. Happy to provide more specific info if I can. App was started with the following parameters: +RTS -N -qg1 -A5m -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15010#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
