sw-engine-fpm segmentation fault when using phpmyadmin

[DickTump]

We have a client using Plesk on his server with a problem when he is using phpMyAdmin. When doing an export of the SQL database in SQL format, the export fails with the following error message: 502 Bad Gateway (nginx). The same time, there is a segmentation fault message in the kernel log: sw-engine-fpm[23044]: segfault at 7365746f7571 ip 0000000000943eab sp 00007fff4200c7f0 error 6 in sw-engine-fpm[400000+cd0000]

For some reason, it does not happen when exporting to a CSV file.

I have already filled in a bugreport at the Plesk website (http://www.parallels.com/support/plesk/bugreport/) more than a week ago, but I don't get any reply.

Does anyone have an idea how to fix this?

Thank you for your response. I have applied the configuration change (the fast cgi buffers) and this seems to have solved the segfault problem.
