#N:harpo:12900009:000:794 harpo!ber Jan 4 19:32:00 1983 I'm looking for help with a kernel problem. I'd like to increase the number of mounted files systems on my vax 4.1bsd beyond 15. When I raised the NMOUNT constant in param.h from 15 to 31 the result was sporadic "panic: memall mfind" crashes under heavy usage. Examing the appropriate source lead me to believe that the constant MSWAPX should be equal to NMOUNT (why are there two constants if they have to be the same?). I upped MSWAPX to 31 and now instead of "panic:memall ..." I get "panic: pagein c_page chgd". Looking at that code prompted me to ask for help. A minor bug in mount and umount was observed. For the record they truncate and rewrite /etc/mtab for each file system. Howver, they don't close it. After 20 mounts. mtab is truncated but can't be written. brian redman
