We are running listserv 1.8d on Solaris 2.7 and using the web interface. All of a sudden we are seeing extremely slow responses from the web interface, and also many web interface errors. this is the error that turns up in the web server error log: [25/Jun/1999:17:40:40] failure: for host 159.142.174.34 trying to GET /cgi-bin/wa, cgi-parse-output reports: the CGI program webstuff/cgi-bin/wa did not produce a valid header (read failed, error is unknown error 145) Any help would be appreciated.
