Ok, I've try to run rgseq from cmdline, and it exited with ctrl+C fine.
Jackd was still up.
But my main problem persists. When I try to record audio,
rg crashes. Jackd is still up and running.
It shows:
WARNING: RecordableAudioFile::initialise: couldn't lock buffer into real memory, performance may be impaired
AlsaDriver - initialisePlayback
WARNING: AudioInstrumentMixer::generateBuffers: couldn't lock ring buffer into real memory, performance may be impaired
the last of of messages are lotta...
and then:

btw. Alsa seems to be properly installed:

thanx for reply. I'm running Fedora1 with atrpms
2.4.22-1.2174.nptl_38.custom kernel.
Jack is starting with jackd -d alsa -d emu10k1 -r 44100 -p 1024 -M -S.
I've set Sequencer->Sync Seq.timer to PCM capture,
switch off Send Midi Clock, set Jack tr.mode to Sync and turned off MMC.
But my problem with crashing RG persists.

Ok, can you try turning off the JACK sync mode completely.  Then try running 
up the sequencer process by itself (rosegardensequencer) and then quitting it 
from the command line with CTRL+C to see if that crashes on exit.

You're still seeing crashing whilst you're starting recording from inside RG 
or on exit or both?
