Description Martin Jost 2009-01-30 21:42:32 UTC

User-Agent: Mozilla/5.0 (X11; U; Linux i686 (x86_64); de; rv:1.9.0.5) Gecko/2008120121 Firefox/3.0.5

I had a bunch of problems with Suse 11.1 which annoyed me without end.

These were the symptoms:
(All these things worked with 11.1 and then suddenly stopped working; so I suspect an update as source of the problem)

- suspend to disk fails
The log told about processes, which didn't freeze.
(Suspend to RAM never worked on my board)

- smpppd needed to be started by hand after each reboot
Although it was enabled to be started on boot

- /var/lock/SuSEfirewall2.booting was mentioned in a log and was still present minutes after booting and after loging in to KDE.

- cyrus-imapd needed to be started manually after some reboots (but not all)

- wwwoffle needed to be started manually after reboot

All these things finally found one solution:
"jexec" hangs on boot.
(Switched back to the console 1 to see the "traffic light" from booting.)
There
Starting jexec....
was the last line and no success/fail behind.
I disabled jexec in yast/system/runlevels, now all the listed symptoms are gone...

What I still don't know, is what jexec is good for, but so far I saw no problems. So I feel much better off without it for the moment...

Reproducible: Always

Steps to Reproduce:
1. update 11.1 to current state (as of 25 Jan. 2009)
2. start system
3. check processes smpppd, wwwoffle and master (from cyrus imapd); try to suspend to disk
Actual Results:
smpppd, wwwoffle and master (from cyrus imapd) aren't started
suspend to disk fails

Expected Results:
processes should be running, suspend to disk should be working.

I found three bugs mentioning jexec, but they desribe different misbehaviour, which I didn't see:
"Bug 461347 - mount problems" also suggests disabling jexec on boot. (Although I never had mount problems)
"Bug 461786 - system cannot mount any additional file systems" is similar in this respect
"Bug 463582 - Installation of JRE 6 update 12 breaks boot (binfmt_misc issue)" explicitely mentions JRE 6 update 12 and jexec together with binfmt_misc. binfmt_misc is mentioned in /etc/rc.d/jexec

Comment 1 Michal Vyskocil 2009-02-02 14:25:37 UTC

Problem is, that I'm fully unable to reproduce this jexec issue. Could you tell me if you have a 32/64bit system, java from openjdk, or sun?

And still don't know what package contains a jexec service. Can you check the rpm -qf /etc/init.d/jexec (is exists), or type me a list of all installed packages?

Comment 2 Martin Jost 2009-02-02 21:07:34 UTC

I've installed the 64 Bit version.
Linux godot 2.6.27.7-9-default #1 SMP 2008-12-04 18:10:04 +0100 x86_64 x86_64 x86_64 GNU/Linux

Ahh, and if this matters, this is a dual core (Intel Core 2 Duo)

> rpm -qf /etc/init.d/jexec
jre-1.6.0_11-fcs

I'll also attach a list of all installed packets.

Comment 3 Martin Jost 2009-02-02 21:08:59 UTC

Created attachment 269391 [details]
list of all installed packets (rpm -qa | sort)

This is the list as of today

Comment 4 Michal Vyskocil 2009-02-04 09:50:50 UTC

The jre-1.6.0_11-fcs is Java from Sun com, isn't it? That's probably the reason, why I was unable found a jexec in /etc/init.d. I'll investigate it.

*** Bug 468970 has been marked as a duplicate of this bug. ***

Comment 6 Michal Vyskocil 2009-02-04 10:34:46 UTC

jexec hangs on 'mount -t binfmt_misc none ${BINFMT_MISC} 2> /dev/null', so it's a definitely a dup of bnc#463582

Use a workaround in comment #12 [1] if you'd like have a jexec service enabled.
