Description Stefano Crocco 2024-09-02 13:49:05 UTC

Application: akonadiserver (6.2.0 (24.08.0))

Qt Version: 6.7.2
Frameworks Version: 6.5.0
Operating System: Linux 6.10.7 x86_64
Windowing System: X11
Distribution: "Gentoo Linux"
DrKonqi: 6.1.4 [KCrashBackend]

-- Information about the crash:
I have configured KMail to check mail from several accounts at given intervals (5 and 30 minutes, depending on the accounts). Starting with akonadi-24.08.0, when KMail is doing this, akonadi sometime crashes.

I've configure akonadi to use the postgresql backend, using postgresql 15.8.

Unfortunately, since this happens during automatic mail checks I don't know if there's a specific account which triggers this behavior.

The crash can be reproduced sometimes.

Fix crash when query is evicted from QueryCache

The eviction code was bugged and caused unrelated entries to be
evicted from m_keys and m_queries. This lead to m_keys holding
an invalid iterator to m_queries, resulting in a crash.
