In strace of the process you can see something like below:
27790 send(3, "<25>May 7 13:42:19 drwebd.real: Total virus records: 5691941\n", 62, MSG_NOSIGNAL) = 62
27790 open("/opt/drweb/drweb32.key", O_RDONLY|O_LARGEFILE) = 4
27790 read(4, "; DrWeb32 v4.16+ Key File\n; Do not edit!\n\n; \37", 45) = 45 <===== here it only reads the first couple of strings, but it should read the whole file.
27790 close(4)
Cause
License key file is corrupted and drweb cannot read from it.
Resolution
Reupload the DrWeb license key as described in KB#112230
