lstsrv-l, I am new to the listserv product and have run into a problem which I'm hoping someone can help. We are running listserv 15.0 under Redhat Enterprise Linux 4.0 (latest patches), including an apache web server and sendmail as the MTA. Our web interface for listserv is version: WA version 2.4.1 R2398 Compiled on Nov 24 2006 00:54:25 The listserv software appears to be working fine in that we can post via email to lists we create. The web interface seems to also be working for all functions we've tested with one glaring exception. Whenever we try to post to a list via the web interface we get the following error message in our web browser: Error - invalid parameter An invalid parameter was passed to the CGI function. Please report this error to the webmaster and make sure to specify the full URL that led to this message. Meanwhile, the listserv.log file shows: 12 Feb 2007 14:09:30 From [ANONYMOUS]@LISTS.UMT.EDU: X-LOGCK 59A54765D9B7270843 AUTHINFO(10.10.9.9) ORGINFO(10.10.9.9) WM: X-POST TESCHO-L VCPU=0.000 TCPU=0.000 T-V=0.000 SIO=0 PGIO=0 Elapsed: 0.000 sec (**%) VCPU=0.000 TCPU=0.000 T-V=0.000 SIO=0 PGIO=0 Elapsed: 0.000 sec (**%) 12 Feb 2007 14:09:31 From [ANONYMOUS]@LISTS.UMT.EDU: X-LOGCK 59A54765D9B7270843 AUTHINFO(10.10.9.9) ORGINFO(10.10.9.9) MAKEDD (MESSAGE 7503278456444403) WM: X-POST TESCHO-L TO: *LIST* *END* 12_Jon Robinson28_testing posting from the web15_NOMIMETAGS: Yes22_TAG: Mime- Version: 1.048_TAG: Content-Transfer-Encoding: quoted-printable51_TAG: Content-Type: text/plain; charset="ISO-8859-1"11_DD: MESSAGE 12 Feb 2007 14:09:31 >>> Error X'00000011' opening file /u01/listserv/ home/7503278456444403.tmp <<< 12 Feb 2007 14:09:31 -> Severity: Warning 12 Feb 2007 14:09:31 -> Facility: Generic error codes 12 Feb 2007 14:09:31 -> Abstract: File/major entity not found 12 Feb 2007 14:09:31 -> I/O mode: Record read 12 Feb 2007 14:09:31 To [ANONYMOUS] @LISTS.UMT.EDU: ***OK*** 0 0 17 VCPU=0.000 TCPU=0.000 T-V=0.000 SIO=0 PGIO=0 Elapsed: 0.000 sec (**%) If any one has some clues for me or would like more information to better diagnose I'd appreciate hearing from you.
