Sorry about my last posting---I hit the wrong key before I finished my question. I'll try this again. This is the console message. Processing file (1001) from GE0013@SIUCVMB PUT <listname> DMSXWS554E No storage available Error 0 while LSVSORT-ing list file. Internal error, postmaster has been notified. This was at 3MG. At 4MG I was able to put the list back out but a couple of days later the listowner got the same error. We're now at 6MG and it appears that things are working alright but---our Systems people would prefer that we not run at 6MG if it's not absolutely necessary. Has anyone else experienced this problem? What is being sorted--- the list itself is less than 100 lines. Is it possible that there is a bug in the LISTSERV software or do we really need to run the machine to 6MG?
