python - Killing individual Apache processes in mod_python -

-

we having problem individual apache processes utilizing large amounts of memory, depending on request, , never releasing main system. since these requests can happen @ time, on time web server pushed swap, rendering unresponsive ssh. worse, after request has finished, python fails release memory wild, results in number 500mb - 1gb apache processes lying around.

we push few requests per second, each request has potential heavy.

what have way kill individual apache process child after has finished serving request if resident memory exceeds threshold. have tried several ways of doing inside mod_python, appears form of system exit results in response not completing client.

outside of gracefuling processes (which want avoid) whenever happens, there anyway tell apache arbitrarily kill off process after has finished serving request? ideas welcome.

as additional caveat, due legacy nature of system, can’t upgrade later version of python, can’t utilize improved memory performance of 2.5. similarly, stuck our current os.

versions: system: red hat enterprise 4

apache: 2.0.55

python: 2.3.5

i'd possible, tremendous hack (and instable) - should set-up process external apache in case, supervise running processes , kill individual apache when goes beyond memory/time predefined limits.

such script can kept running continuously mainloop performs it's checks every few seconds, or put in crontab run every minute.

i see no reason try inside serving processes themselves.

c# - Is it possible to remove an existing registration from Autofac container builder? -

something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
