I'm not seeing terrible problems but I'm not using MMAP yet :-) Make sure you have this patch installed in your INN: I forget where it came from - may have been direct from rsalz) and patched it on to INN 1.4 here. The relevant area, as kluged, now reads (around line 82 in site.c): if (AmRoot) xchown(name); if (cp) { if (cp->fd >= 0) syslog(L_ERROR, "DEBUG ERROR SITEspool trashed:%d %s:%d", cp->fd, sp->Name, i); WCHANremove(cp); RCHANremove(cp); SCHANremove(cp); close(cp->fd); cp->fd = i; return TRUE; } sp->Channel = CHANcreate(i, CTfile, CSwriting, SITEreader, SITEwritedone); if (sp->Channel == NULL) { ----------------------- That fixes a file descriptor leak in INN. I think you should probably re-compile with MMAP off if it is on, and put this patch in. Then re-install the re-linked images. Just out of paranoia I'd run fsck on your news partition, rebuild your history files, and do an expireover -s if you are using the NOV database. Depending on your load you might also want to consider these options in your kernel config file: MAXUSERS 256 options "CHILD_MAX=128" options "OPEN_MAX=128" options "NMBCLUSTERS=512" But you should pick your own numbers for these. My average uptime is out to 4 days now on my heaviest hit box, the other boxes that have lighter load have very good uptimes. I have also noticed very nice performance improvements over the earlier kernels. The failures that I am seeing are scsi buffer already done freezups. About once a week on my 4 gig news harddrive.
