Hi All,

I had problems with blast version 2.0.6 (I guess), sometimes it crashed
and it took me while to look at the syslog of our server to find out
that it was killed by the operating system (IRIX 6.5). 

The reason was that blastpgp installed a signal handler to catch
segmentation faults and this handler itself caused a segmentation fault.
To prevent an endless recoursion it was killed by the os (that was the
message in the syslog). It's along time ago and I don't realy remember
;-( but I think blastpgp was terminated without printing any message.

Is there anything in your syslog?
	good luck,
