My esp8266 module restarts when a timer function is called. esp module restarts when a push message from server is processed.but if a timer is not used in the process it works perfectly fine, else if tmr.alarm function used it restarts following a push message from server.can anyone please find me a better solution to this problem.
my code is posted below

deviceId = wifi.sta.getmac()

-- IN = 8, -- GPIO02
-- OS = 4, -- GPIO02
-- OP = 5, -- GPIO14
-- RS = 1 -- GPIO05
IN = 7, -- GPIO14
OS = 4, -- GPIO02
OP = 5, -- GPIO04
RS = 1 -- GPIO05
}
count=6
gpio.mode(PINS.IN, gpio.OUTPUT)
gpio.mode(PINS.OP, gpio.OUTPUT)
gpio.mode(PINS.OS, gpio.OUTPUT)
gpio.mode(PINS.RS, gpio.INT, gpio.PULLUP)

gpio.write(PINS.IN, gpio.HIGH)
gpio.write(PINS.OP, gpio.LOW)
if gpio.read(PINS.OP) == 1 then
gpio.write(PINS.OS, gpio.LOW)
else
gpio.write(PINS.OS, gpio.HIGH)
end

RS_F = false
gpio.trig(PINS.RS, "up", function(level)
if level == 1 then
if RS_F then
node.restart()
else
if wifi.getmode() ~= 2 then
RS_F = true
start_ap()
else
print("already on ap")
end
end
end
end)

 if count>=1 then
