Bug ID: 397774
Summary: SIGPIPE when killing local server
Product: kstars
Version: 2.9.8
Platform: Other
OS: Linux
Status: UNCONFIRMED
Severity: crash
Priority: NOR
Component: general
Assignee: mutla...@ikarustech.com
Reporter: eric.dejouha...@gmail.com
Target Milestone: ---
During robustness tests, I obtained a crash when randomly killing the local
indiserver while the Scheduler is running jobs. In that situation, a SIGPIPE
fires while writing commands through the server pipe.
Thread 1 "kstars" received signal SIGPIPE, Broken pipe.
