• The "enable streamlined parallel" configuration parameter is set to 1.
•  An "infected with signal 11" error with a stack trace may be reported in the SAP ASE error log when you try to insert a row into a proxy table, for example:
   
• (ASE 15.7 SP141)
  Current process (0x19000d) infected with signal 11 (SIGSEGV)
  Address 0x0x000000000091640d (StatsDesc::addStatsUpdateInfo(short*, int, _cs_datetime*)+0x19db3), siginfo (code, address) = (1, 0x0x000000000000001c)
   
• (ASE 16.0 SP03 PL07)
  Current process (0x35001b) infected with signal 11 (SIGSEGV)
