CertificateCEMController: String index out of range: -1

Started receiving this error out of the blue. It doesn't seem to correlate with an expired certificate. The error repeats every minute and is not related to any outbound messages.

Could this be caused by someone trying to send me a file (with max retries set to infinity, and wait time set to one minute)?

"CertificateCEMController: String index out of range: -1"





I got the same,

Out of the blue, _every_ minute I get this 'CertificateCEMController' message:

[8:31:45 AM] CertificateCEMController: Certificate with issuer CN=COMODO SHA-256 Organization Validation Secure Server CA, O=COMODO CA Limited, L=Salford, ST=Greater Manchester, C=GB and serial not found

Things to note:
- Certificates (and cert chains) are valid and AS2 is still operating as far as I can tell.
- Reboot of AS2 server did not fix the error message. Still turn up every minute after reboot

Ta :)
