PGP Command Line 9.5 and AIX 5.3 CPU 100% (non-root user)
PGP Command Line 9.5.2 (AIX) hangs decrypting a 36 MByte compressed armored file
We are using "PGP Command Line 9.5.2 build 654, (c) 2005" for both file encryption and decryption on AIX 5.3.
We use PGP to encrypt a 267 MByte file down into 36 MByte compressed armored file.
The PGP encryption command exits with zero (success).
We try to decrypt this 36 MByte compressed armored file with PGP.
We try the same decryption with the "--verbose" flag.
The PGP decrypt command logs that it has opened the keyrings and then logs:
"Decoding file /ftp/omnipay/in/gcms_tmp.oenc... 1% (... MB)"
The percentage climbs 1%, 2% up to 45% promptly and then hangs at:
"Decoding file /ftp/omnipay/in/gcms_tmp.oenc... 45% (15.5MB)"
A system monitoring tool ("topas") shows that the pgp decrypt process is still consuming CPU time (about 80% CPU) despite the apparent hang (perhaps an infinite loop??).
How can we get PGP to decrypt this file?
