strange messages in the systemd journal

Question

I'm running systemd version:

systemd 245 (245.4-4ubuntu3.2)
+PAM +AUDIT +SELINUX +IMA +APPARMOR +SMACK +SYSVINIT +UTMP +LIBCRYPTSETUP +GCRYPT +GNUTLS +ACL +XZ +LZ4 +SECCOMP +BLKID +ELFUTILS +KMOD +IDN2 -IDN +PCRE2 default-hierarchy=hybrid

on 5.8.0-54-lowlatency #61~20.04.3

For some reason my services started spamming the system log with these messages:

It doesn't look like the messages that my application would write. It seem more system related. Any ideas would be helpful. There is plenty of disk space, so far.

Looks like some log records formatted like `dmesg`, split by the word bounds. Large numbers are timestamps, etc. Assembled message seems to be like `[1633203968.551844999] ERROR: ModuleID=8 Errcode=8 X=0 E=1 T=1 /:-1/:`. Are you sure your application couldn't output this? — Nikita Kipriyanov, Oct 02 '21 at 20:25
@NikitaKipriyanov - I'm fairly certain that it isn't my application. But it could the libraries I link with. — ilya1725, Oct 02 '21 at 20:58

Found it. One the libraries we are using is sending this message.
