Rudder

This happened after a reboot where Rudder was behaving very strangely (slow, no connection to DB, etc). See #16051.

The trace is:

Caused by: java.lang.RuntimeException: BackendException: An error occured; cause was: java.lang.Error: null

Which matches that code:

231 trait PooledConnectionProvider[LDAP <: RoLDAPConnection] extends LDAPConnectionProvider[LDAP] {
232  self:UnboundidConnectionProvider =>
233
234  def poolSize : Int
235  def ldifFileLogger:LDIFFileLogger
236
237  // for performance reason, operation on pool can't be wrapped into ZIO
238  protected lazy val pool = try {
239    new LDAPConnectionPool(self.newUnboundidConnection, poolSize)
240  } catch {
241    case ex: LDAPException =>
242      LDAPConnectionLogger.error(s"Error during LDAP connection pool initialisation. Exception: ${ex.getDiagnosticMessage}")
243      throw new Error(ex.getDiagnosticMessage)
244  }
