TMM was cored due to memory corruption caused by a double free in form based SSO. A forms-based SSO control failing to decrypt could lead to a double free. The decryption failure message is logged in LTM log.
Traffic disrupted while tmm restarts.
Double free and TMM core could happen only if forms-based SSO control failed to decrypt.
This issue has no workaround at this time.
Forms - Client Initiated SSO authentication handles decryption failure correctly.
