dying via an abort() call. They are usually placed in code to stop a program when its doing something that violates some expectation. The idea is to force a coredump to collect a backtrace to get an idea of what's wrong. At line 8 the code throws a protocol exception and this probably comes near the code mentioned in line 9. So, something unexpected in the imap protocol is probably causing the issue. 1667418 3 dennis.schridde 2017-03-21 09:06:16 +0000 DrKonqi suggested both bugs, this and duplicates of the other, as possible duplicates of a crash that I was experiencing. I assumed that was because the backtrace was the same. 1667517 4 sgrubb 2017-03-21 18:23:35 +0000 In src/server/connection.cpp at line 404, there should probably be a try/catch around the Protocol::serialize() call: void Connection::sendResponse(qint64 tag, const Protocol::Command &response) { if (Tracer::self()->currentTracer() != QLatin1String("null")) { Tracer::self()->connectionOutput(m_identifier, QByteArray::number(tag) + ' ' + response.debugString().toUtf8()); } QDataStream stream(m_socket); stream << tag; Protocol::serialize(m_socket, response); } because way down at the bottom in src/private/datastream_p_p.h at line 92, we find: if (mDev->write((char *)&val, sizeof(T)) != sizeof(T)) { throw Akonadi::ProtocolException("Failed to write data to stream"); } Does this help? 1667578 5 dvratil 2017-03-22 00:43:51 +0000 *** Bug 377871 has been marked as a duplicate of this bug. *** 1667582 6 sgrubb 2017-03-22 01:36:24 +0000 Some information printed to the console around the time of another abort: org.kde.pim.akonadicore: Got a stale notification for an item which was already removed. 2061954 "" org.kde.pim.akonadicore: Got a stale notification for an item which was already removed. 2061955 "" org.kde.pim.akonadicore: "QLocalSocket: Remote closed" "/tmp/akonadi-sgrubb.jJx32f/akonadiserver-cmd.socket" org.kde.pim.akonadicore: Socket error occurred: "QLocalSocket: Remote closed" org.kde.pim.akonadicore: Error on fetching collection statistics: "" org.kde.pim.akonadicore: "QLocalSocket: Remote closed" "/tmp/akonadi-sgrubb.jJx32f/akonadiserver-cmd.socket" org.kde.pim.akonadicore: Socket error occurred: "QLocalSocket: Remote closed" org.kde.pim.akonadicore: "QLocalSocket: Remote closed" "/tmp/akonadi-sgrubb.jJx32f/akonadiserver-ntf.socket" org.kde.pim.akonadicore: "QLocalSocket: Remote closed" "/tmp/akonadi-sgrubb.jJx32f/akonadiserver-ntf.socket" org.kde.pim.akonadicore: "QLocalSocket: Remote closed" "/tmp/akonadi-sgrubb.jJx32f/akonadiserver-ntf.socket" org.kde.pim.akonadicore: "QLocalSocket: Remote closed" "/tmp/akonadi-sgrubb.jJx32f/akonadiserver-ntf.socket" org.kde.pim.akonadicore: "QLocalSocket: Remote closed" "/tmp/akonadi-sgrubb.jJx32f/akonadiserver-ntf.socket" org.kde.pim.akonadicore: "QLocalSocket: Remote closed" "/tmp/akonadi-sgrubb.jJx32f/akonadiserver-ntf.socket" org.kde.pim.akonadicore: "QLocalSocket: Remote closed" "/tmp/akonadi-sgrubb.jJx32f/akonadiserver-ntf.socket" "Unknown error." org.kde.pim.akonadicore: Error on fetching collection statistics: "" "Unknown error." org.kde.pim.akonadicore: Error on fetching collection statistics: "" 1669497 7 dvratil 2017-04-01 10:32:09 +0000 Git commit da7070a7facb3c2f91c03b28c36ba5b929b89a42 by Daniel Vrátil.
