Intermittent crash with JPilot while syncing

[CoSoCo]

Every ~ 10 runs I observe some kind of crash with latest JPilot.
When I run it with jpilot -d I often see caught signal SIGCHLD, but mostly without a notable crash.
Here a typical example in the 45th last line:
JPilot with signal SIGCHLD_2.log

There are different types of crashes, where I have no clue, what are the conditions for:

1. Logging pane stops listing, and the complete GUI freezes.
2. Sometimes I can close the app by the X button in the window title.
3. But sometimes not, so I must kill it.
4. Sometimes the sync has completed (sync button is again normal), but in few cases not.
5. Sometimes after the cases above, on restart, all or partly custom settings and window size are lost, but sometimes not.
6. Sometimes after the cases above, on restart, a complete initial sync is processed, which takes much longer than normal.
7. Often changing the window focus from JPilot to another App makes a crash much more probable.

Fortunately I never observed a real data loss.

Maybe some ideas on that?

Here the last lines of a crash with GUI freeze again.

Often I see jp_pref_write_rc_file() as the last action before the crash.

On the next start I saw:

• All preferences were lost
• The sync took unusually long time, because it seems, that all databases were copied newly instead only syncing changed records.

Honestly, from the information provided I do not know what the root cause is.

To narrow down the problematic location:

1. Can you try to sync multiple times again with the Media plugin disabled?
2. If that works for 10-20 times, then try the same for Expense, then for KeyRing, i.e., disable one plugin after the other.

For generating additional information, please monitor which files are modified, see inotify-tools: inotifywait.

I now can tell, that I tried several times without my Media plugin, but the crash still happens sometimes. It happens much more often since using Ubuntu 24.04 than with 22.02. In furture I will use it without Expense, Keyring and SQLite, because I don't need theese data bases. Am 18.03.25 um 20:45 schrieb Elmar Klausmeier:

I have new data:
Mostly, the sync seems completed, as on my Palm Treo 680 I see normal completion with Hotsync protocol with no errors, but the JPilot desktop application is frozen.
The last message in syslog was: 2026-07-01T01:04:24.043005+02:00 W541 jpilot.desktop[880242]: command=100 [PmTraceDum
