[php-maint] Bug#656424: php-mdb2: Spurious file system accesses

[Matthias Urlichs]

Package: php-mdb2
Version: 2.5.0b2-1
Severity: important

Running a SQL statement results in a couple of very strange spurious file system accesses.
Frankly I couldn't believe my eyes.

(This is the mysql driver. I'm trying to set up roundcube.)

strace output:

0xbff56488) = -1 ENOENT (No such file or directory)
