Howdo, We're running Solaris 2.7 with Listserv 1.8d We are experiencing occasional unexplained crashes of Listserv where it just dies. Nothing is logged, no crash dumps - nothing. The crashes happen at varying times during the day. We have 512Mb. RAM on that machine and 500+ lists, most of which are small to medium, a couple are > 1500 subscribers. We are up to date with sendmail too. Is kernel tweaking maybe appropriate here, or more RAM? Lsoft in the past have mentioned these crashes a virtual memory issue ... Has anyone else experienced these crashes? Thanks for any info Scotty -- Steve Howie University of Guelph, Guelph, Ontario CANADA "If it's not Scottish - it's C-R-R-R-R-R-R-R-R-A-A-A-A-A-A-A-P!!"
