ClamAVエラー - Extrasensory Perception + ER + Blog

日次でサーバのウイルススキャンを実行していますが、10/23から何故かウイルススキャンが終わらない事象が発生。
それどころか、clamscanコマンドをリダイレクトしているファイルが肥大化してディスクフルを引き起こす始末。

ファイルをのぞいてみると次のエラーがひたすら出力されている。

LibClamAV Error: mpool_malloc(): Attempt to allocate 8388608 bytes.

バグかと思い、長らく更新していなかったclamavの更新を実行。

とりあえずエラーを吐かずに正常終了するようになりました。
