Orthanc on Ubuntu 22.04 LTS crashing

General
1

Dear all,

I have an Ubuntu 22.04 machine over which Orthanc 1.10 was installed from the main repositories. For some time, Orthanc was working fine, but as soon as I patched the OS with the latest patches, Orthanc started crashing when uploading any data, with the error “free(): double free detected in tcache 2”.

Note that I have been able to re-create the problem on three machines, and it is clear that any DICOM file will crash Orthanc.

Is anyone experiencing this problem, or does anyone have an idea how to solve it?

Thanks in advance.

Following is the tail of the log created by Orthanc before the crash

Hello,

I think this error is very similar to this Ubuntu bug report.

There are chances that this is an issue with the DCMTK package of Ubuntu, not with Orthanc. To confirm this, try to start the following command in one terminal:

$ cd /tmp
$ storescp 2000

Then, try to send a DICOM instance from another terminal:

$ storescu localhost 2000 sample.dcm

If one of these commands crashes, this is definitely an issue in the DCMTK packages. For reference, I know that the same issue occurs on Ubuntu 20.04 and can be solved by typing:

$ sudo apt install dcmtk=3.6.4-2.1build2 libdcmtk-dev=3.6.4-2.1build2 libdcmtk14=3.6.4-2.1build2

Regards,
Sébastien-

A big thanks for pointing out the dcmtk library. Actually testing with storescu and storescp, nothing came out as they did not crash, but Orthanc now works after downgrading libdcmtk16 with version 3.6.6-5ubuntu0.1~esm2 to version 3.6.6 5. The bug seems to have lurked in the ESM packages. I have reported my findings on the bug report you mentioned.
