Hi,Stack trace of thread 468215: #0 0x0000000000404610 strlcpy (vacation + 0x4610) #1 0x0000000000402e0e main (vacation + 0x2e0e) #2 0x00007f2a6f8a0088 __libc_start_call_main(libc.so.6 + 0x2a088)
Your citation is hard to read again. Are you using Google Mail Web interface? I think they wrap all lines after 72 characters. Please use something else to help the people you ask for help.
Thank you for the data point. Please report that to the Fedora project [1][2].#3 0x00007f2a6f8a014b __libc_start_main@@GLIBC_2.34 (libc.so.6 + 0x2a14b) #4 0x0000000000403525 _start (vacation + 0x3525) ELF object binary architecture: AMD x86-64The root cause could be an unexpected message header. There are only four strlcpy() calls in the source package for Fedora. One is to copy the username as looked up from the passwd database, and the other calls copy information from the From_ line (the first line of the vacation input) or from the From: header. The strlcpy() manpage says: strlcpy(3bsd) and strlcat(3bsd) are designed to crash if the input string is invalid (doesn't contain a terminating null byte). Do the failing deliveries have the same sender?At first I was thinking it had something to do with corrupt messages/headers that occurred during the process of migrating the users, but after John's comment that seemed to indicate that wasn't the case, I installed the vacation binary from the vacation package from a fedora38 system: # rpm -q vacation vacation-1.2.7.1-24.fc38.x86_64 That fixed it. The last changes to the vacation package for fedora40 were back in Jan, so not sure how a bug like this wouldn't have been caught in that time.
