Yeah, sorry for the confusion ;)

I had 4 einstein processes running, I suspended 2 of them, and 2
abc-finder started, but 1 einstein is left in memory (the first one,
in sleep status)

# ps -eo pid,user,stat,comm | grep boinc
14097 boinc    SNl  einstein_S5R4_6
14100 boinc    RNl  abc-finder_1.03
14110 boinc    RNl  abc-finder_1.03
14150 morph    Ss   boincmgr
16603 boinc    SN   boinc
20173 boinc    RNl  einstein_S5R4_6
25929 boinc    RNl  einstein_S5R4_6

Configuration key changed, and just after restart, everything seems pretty ok:

# ps -eo pid,user,stat,comm | grep boinc
14459 boinc    SN   boinc
14485 boinc    RNl  einstein_S5R4_6
14488 boinc    RNl  einstein_S5R4_6
14489 boinc    RNl  abc-finder_1.03
14490 boinc    RNl  abc-finder_1.03
14497 morph    Ss   boincmgr

Then, keep suspending and resuming, I got:

# ps -eo pid,user,stat,comm | grep boinc
14459 boinc    SN   boinc
14485 boinc    RNl  einstein_S5R4_6
14497 morph    Ss   boincmgr
14525 boinc    RNl  abc-finder_1.03
14526 boinc    RNl  abc-finder_1.03
14570 boinc    SNl  abc-finder_1.03
14583 boinc    RNl  einstein_S5R4_6

I'm attaching the log generated with

grep "25-Aug-2008 22:5" /var/lib/boinc-client/stdoutdae.txt

yeah, here it's matter of minuts, for garli was some hours (then I
realized there was something that occupied all my memories and I've
restarted the boinc client).

Cheers,
Sandro
