Stream IO exception : "TCP/IP protocol is mismatched between the Server and Web Extensions"

[fvanderbiest]

On Ubuntu Linux 7.04 (actually a chroot), the Mg server sometimes outputs this kind of message (while using ajaxtiledviewersample.php) :

(6311|2448243600) A stream IO exception occurred. The TCP/IP protocol is mismatched between the Server and Web Extensions.

Please install the same version of Server and Web Extensions.

Exception occurred in method MgStreamParser.ParseStreamHeader at line 91 in file System/StreamParser.cpp

Yet, it does not seem to have any visible consequence, from a user point of view.

Mg was built from svn rev 2448.

I am seeing this as well on RH 4 ES, compiled from the 2.0 tarball

(2694028192) A stream IO exception occurred. The TCP/IP protocol is mismatched between the Server and Web Extensions. Please install the same version of Server and Web Extensions. Exception occurred in method MgStreamParser.ParseStreamHeader at line 91 in file System/StreamParser.cpp

(2694028192) The connection is not open. Exception occurred in method MgSiteConnection.GetCurrentUserInfo at line 382 in file System/UserInformation.cpp

terminate called after throwing an instance of 'MgConnectionNotOpenException*'

This was fixed with submission r3049 & r3050; a few days after 2.0.0 was posted.

Hi Zac, is there anything in the server's error.log file around the time when this happened? Tom

Just that message I included, nothing else.

I was seeding a tiled map using openlayers, the only calls being made where GETTILE against the server using SHP files

Please re-test against 2.1 and let us know if this is still an issue (or close if has been fixed). Will close this ticket if no response by next ticket cleanup cycle.
