Output Memory allocation error (0xc0000017)

[Burn Zero]

Hi,

Freeradius server version : 3.0.17, 64bit
OS : CentOS 7.2

We have setup Freeradius to authenticate users to get access to WiFi.
Freeradius is connected to Active Directory servers for authentication.

Recently Freeradius logged the message "NT_STATUS_ACCESS_DENIED" in the
authentication logs and users were not authenticated. Additionally, I can
see the below logs in Freeradius:

ERROR: (3978) ntlm_auth: ERROR: Program returned code (1) and output
'NT_STATUS_NO_MEMORY: Memory allocation error (0xc0000017)'

Auth: (3978) Login incorrect (ntlm_auth: Program returned code (1) and
output 'NT_STATUS_NO_MEMORY: Memory allocation error (0xc0000017)')

On the another day we got the same issue, same error message and in the
Freeradius logs, we got:

ERROR: (43458) mschap: ERROR: Program returned code (1) and output 'Memory
allocation error (0xc0000017)'

Auth: (43458)   Login incorrect (mschap: Program returned code (1) and
output 'Memory allocation error (0xc0000017)')

When we rejoin the Active Directory domain, the issue gets resolved. Not
sure where the issue lies. Kindly help me.

Thank you.
