_The configuration: 60830,UNIX V.3,16MB _The Situation: 2MB for BUFFERS 'sync' stops all terminal/system activity for some seconds ( until buffers are written to disk ? ) 1MB for BUFFERS no troubles with sync ( of course 2MB BUFFERS is preferable, but users complain about terminals freezing for no obvious reason ) _The question: Is it normal/ok for sync to freeze terminal activity ? I am posting this for a friend of mine who does not read netnews, so please respond by e-mail. I will post a summary if there is enough interest.

(Ok! Done...) I hope there will be more responses in comp.unix.questions plus comp.unix.wizards plus comp.bugs.sys5 ! Followups go to comp.unix.wizards. Please respond by e-mail. I will post a summary if there is enough interest. thanx Erwin Eder -- +---/~~~~\---------------+--------------------------------------------+ | / \ <-- this is | and this uunet!mcvax!tuvie!atbull!ee | | \____/ a tree. | is me --> In-Real-Life Erwin Eder | +-----||-----------------+--------------------------------------------+
