Hi, 
We occasionally find that if tot_size is greater than 1024（sizeof(job_rec)）,two lines will be merged into one line in the jobcomp txt log.So we add this in slurm_jobcomp_log_record (jobcomp_filetxt.c):

snprintf(job_rec, sizeof(job_rec), JOB_FORMAT, xxx);
tot_size = strlen(job_rec);
----add this----
if (tot_size == (sizeof(job_rec) - 1 )){
        job_rec[sizeof(job_rec) - 2] = '\n';
}
