Chimerscan 0.4.5 runs for days and then system kills it

I have some paired read files that range from 1.8Gb to just under 3.0Gb.
Chimerascan works on the smallish test files distributed with the software.
Chimerascan works on some of my files but runs for days then the system kills it

The log files suggest that the initial runs complete through

isize_dist.txt, breakpoint_bowtie_index.log, and tmp_singlemap_seqs.txt

Here are the last lines of the LSF error file:

The program completes for files as large as 3.1Gb as well as smaller files near 1.8Gb but fails on many intermediate sized files.

Same problem. I split the files into 2 smaller files but the problem occurs again.

Does someone know the reason and a possible solution?
