One task completed and validated (sixtrack_lin32_4465_pni.linux, boinc 7.2.0 (X64)). Looks OK.

Update: in standalone mode, sixtrack completed in ~6h as expected.

Communication problem(s) between sixtrack and boinc_client, something wrong in init_data.xml?

I've noticed this for a couple of days. Task error logs (stderr.txt) are filling with "... No heartbeat from client for 30 sec - exiting" and end with "Compute error" (-226 (0xffffffffffffff1e) ERR_TOO_MANY_EXITS). Resetting project had no effect.

Unpacked one of the failing tasks .zip file into separate directory and ran sixtrack there - .fort files are being updated and growing, it hasn't crashed yet.

sixtrack_lin64_4463_pni.exe (in projects dir)
'file' reports it as "sixtrack_lin64_4463_pni.exe: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), statically linked, for GNU/Linux 2.6.9, not stripped", guess it isn't really a 64-bit app?

Had a look at my tasks:
Inclonclusive (1):
http://lhcathomeclassic.cern.ch/sixtrack/workunit.php?wuid=9018280
Error (306):
first one: http://lhcathomeclassic.cern.ch/sixtrack/workunit.php?wuid=8972676
Also, some tasks seem to be OK:
http://lhcathomeclassic.cern.ch/sixtrack/workunit.php?wuid=9086803

All tasks in "Error" list belong to SixTrack v446.03 (pni)
