Hi, I am observing that the first 4 bytes are changed to zero, let me know what is the reason for this. before insert: (gdb) p instance $1 = (ngp::timer_manager::timer_instance_t &) @0x7fffb610e118: {padding = *1919*, id = 2, api_id = 1, next = {__d = { __r = 98595033760891}}, period = {__r = 20000}, max_iterations = -1, running = false, user_data = 0x0, target_identifier = 0, startAddr = 0x5555555c22cb <boost::interprocess::ipcdetail::CtorArgN<ngp::timer_manager::timer_instance, false, int, unsigned long&, unsigned long&, std::chrono::time_point<std::chrono::_V2::steady_clock, std::chrono::duration<long, std::ratio<1l, 1000000000l> > >, std::chrono::duration<long, std::ratio<1l, 1000l> >, int&, void*&, unsigned int&>::construct<0ul, 1ul, 2ul, 3ul, 4ul, 5ul, 6ul, 7ul>(void*, boost::interprocess::ipcdetail::bool_<false>, boost::container::dtl::index_tuple<0ul, 1ul, 2ul, 3ul, 4ul, 5ul, 6ul, 7ul> const&)+401>, startTime = 177880440076688, interval = 20000} *after insert (queue->insert(instance))* (gdb) p instance $4 = (ngp::timer_manager::timer_instance_t &) @0x7fffb610e118: {*padding = 0*, id = 2, api_id = 1, next = {__d = { __r = 98595033760891}}, period = {__r = 20000}, max_iterations = -1, running = false, user_data = 0x0, target_identifier = 0, startAddr = 0x5555555c22cb <boost::interprocess::ipcdetail::CtorArgN<ngp::timer_manager::timer_instance, false, int, unsigned long&, unsigned long&, std::chrono::time_point<std::chrono::_V2::steady_clock, std::chrono::duration<long, std::ratio<1l, 1000000000l> > >, std::chrono::duration<long, std::ratio<1l, 1000l> >, int&, void*&, unsigned int&>::construct<0ul, 1ul, 2ul, 3ul, 4ul, 5ul, 6ul, 7ul>(void*, boost::interprocess::ipcdetail::bool_<false>, boost::container::dtl::index_tuple<0ul, 1ul, 2ul, 3ul, 4ul, 5ul, 6ul, 7ul> const&)+401>, startTime = 177880440076688, interval = 20000} here queue is typedef bip::multiset<timer_instance_t, timer_comparator, ShmemAllocator_Timer> timer_queue_t; timer_queue_t* queue; typedef struct alignas(4) timer_instance { uint32_t padding; timer_id_t id; uint64_t api_id; timestamp_t next; millis_t period; int32_t max_iterations; // handler_type_t handler; bool running; void* user_data; uint32_t target_identifier; void* startAddr; uint64_t startTime; uint64_t interval; } Regards, Murali Kishore On Sat, Sep 28, 2024 at 3:17 PM Murali Kishore <bmuralikishore@gmail.com> wrote:
Thanks, it worked.

// Define the unordered_map type typedef boost::unordered_map<timer_id_t, timer_instance_t, std::hash<timer_id_t>, std::less<timer_id_t>, MapAllocator> timer_instance_map_t;
You have to use std::equal_to<timer_id_t> rather than std::less<timer_id_t>. Please try and let us know if that solves your issue.
