[Bioperl-l] StandAloneBlast crashing due to "too many open files"

[Michael Muratet]

Greetings

Using bioperl 5.6.0 to compare a list of clones against itself for 
reduncancy. After checking fifteen-hundred or so, the following 
exception occurs:

------------- EXCEPTION  -------------
MSG: Could not open tempfile /tmp/mmuratet.4487.4491: Too many open files

STACK Bio::Root::IO::tempfile 
/usr/lib/perl5/site_perl/5.6.0/Bio/Root/IO.pm:500
STACK Bio::Tools::Run::StandAloneBlast::new 
/usr/lib/perl5/site_perl/5.6.0/Bio/Tools/Run/StandAloneBlast.pm:354
STACK toplevel ./alignAll.pl:29

Watching /tmp while the program runs doesn't show a lot of files 
building up so I assume the delete on exit part of IO.pm is working OK. 
Adding `rm /tmp/mmuratet*` (the root name of the temp files) doesn't 
help either.

Anybody have any ideas where to look?

Thanks.

Mike
