http://bugzilla.novell.com/show_bug.cgi?id=628298 http://bugzilla.novell.com/show_bug.cgi?id=628298#c1 --- Comment #1 from Jan Engelhardt 2010-08-04 12:21:33 UTC --- Created an attachment (id=380539) --> (http://bugzilla.novell.com/attachment.cgi?id=380539) strace -p affected process Here is a log where this hang occurs, and where a.o.o was able to continue -- which is usually not the case and the log just ends after read(4,. 1280923968.837960 write(4, "\200y\1\3\1\0`\0\0\0\20\0\0009\0\0008\0\0005\0\0\210\0\0\207\0\0\204\0\0\26"..., 123) 1280923968.838691 read(4, "\26\3\0\0:\2\0", 7) = 7 1280924115.310855 time(NULL) = 1280924115 1280924115.311186 time(NULL) = 1280924115 Which means that between writing the SSL query and getting a response, almost 45 seconds passed. That alone is _highly_ suspect given most other queries are instantaneous. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

http://bugzilla.novell.com/show_bug.cgi?id=628298 http://bugzilla.novell.com/show_bug.cgi?id=628298#c3 --- Comment #3 from Jan Engelhardt 2010-08-04 14:37:15 UTC --- Project links openSUSE.org -> api.opensuse.org/ Package links Black_Ares:11.3/aaa_base -> openSUSE.org:openSUSE:11.3 +8000 more The problem is that the BSRPCs are not time-limited AFAICS, so if the kernel does not give my local OBS any data back (for whatever reason there is, be it network breakdown or a screwup of the Novell proxies), it hangs basically forever. With a timeout it could at least self-retry so that I do not have to manually kill the hanging srcserver subprocesses to get things going again. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
