ULTRIX V4.3, DECmcc V1.3 SSB, DECnet/OSI V5.1 on DECstation 5000/240 w/128MB. When starting notifications using MCC_ICONIC_MAP command, the command is followed by many, many, many lines of "Socket Failure: too many open files". Also displayed are perhaps one window for each corresponding message above indicating something about "insufficient buffer space to handle request". This looks like a system tunning problem, but since I'm relatively new to ULTRIX, I don't really know what to bump up or where to look. I did increase the various parameters called out in the installation guide and did successfully rebuild the kernel. Any help on this greatly appreciated. Al

You can modify it (to 1024 for example) by editing the file /sys/conf/mips/param.c and rebuilding the kernel. Another ULTRIX parameter controlling the max number of open file for the whole system is MAXUSERS that can be increased by modifying its value in /usr/sys/conf/mips/MACHINE_NAME Regards.

| 4909.2 | Bumped it up but now no incoming events! | LICAUS::LICAUSE | Al Licause (264-4780) | Wed Apr 21 1993 08:42 | 20 | 
|     Pierre,
    
    Thanks very much.
    
    In working with Jack Davisson at the Colorado CSC, we decided to bump
    the max_nofile to 4096 and smmax from the recommended value of 1024 to
    2048.
    
    Now I am able to start all notification requests w/o getting the error
    messages.
    
    Now I'm not seeing any incoming notifications in the iconic map
    notification window even though I can issue a GETEVENT and see it
    come in at the FCL level.
    
    We'll keep trying and hopefully get to a happy medium....(i.e.something
    that works!)
