We haven't heard of similar reports, but there have been a couple of 
crashers in DBD::Pg. It seems that they are typically segmentation 
faults, not bus errors (10), but it might still be useful to check if 
DBD::Pg update would help.

 From https://rt.cpan.org/Public/Dist/Display.html?Name=DBD-Pg ticket 
127847 I found this DBI debug suggestion

export DBI_TRACE=10

What I have used sometimes is to log directly to a debug log file:

export DBI_TRACE=10=/path/to/dbi-debug.txt

See https://metacpan.org/pod/DBI#DBI_TRACE


There are also other issues open at github:
