[maker-devel] MAKER seg faulting

[Carson Holt]

So MAKER is written in Perl, and Perl can’t really seg fault (it doesn’t give developers that kind of low level access to memory). However if you are using MPI, then it could be causing a seg fault, or one of the programs MAKER is calling could be seg faulting (like BLAST).

So if you are using MPI, let me know which flavor and I can make suggestions (for example MVAPICH2 is incompatible with programs that do system calls, and OpenMPI may require special setting for LD_PRELOAD to work properly with shared libraries). If your not using MPI, then you will need to look at the installed programs MAKER is calling and reinstall them, update them, or roll back a version (i.e. BLAST, Exonerate, etc.)
